[texts]Observing System Forecast Experiments at the DAO - Atlas, Rober
Since the advent of meteorological satellites in the 1960's, numerous experiments have been conducted in order to evaluate the impact of these and other data on atmospheric analysis and prediction. Such studies have included both OSE'S and OSSE's. The OSE's were conducted to evaluate the impact of specific observations or classes of observations on analyses and forecasts. Such experiments have been performed for selected types of conventional data and for various satellite data sets as they beca...

[texts]Stability of human sera collected for clinical chemistry determinations - Townsend, F. M
Problems in collecting and shipping human sera for clinical chemical analyses affect their stability and require proper preservation methods. It is shown that glutamic pyruvate transaminase is very unstable and serum cannot be shipped unless the shipping time is carefully controlled and is less than two days under refrigeration. A limit of four days handling time and avoidance of light exposure are required in bilirubin testing of specimens...

The Rolls-Royce Transit Anemometer was applied to several rigs in the Whittle Laboratory. These included a 14 inch calibration jet, to demonstrate the intrinsic accuracy of the machine, and a static turbine cascade in which midspan traverses were produced of the entire duct and a boundary layer. Both of these plots accorded well with previous data and were very much more easily obtained. Data from a rotating cascade was encouraging...

[texts]Theory underlying the peripheral vision horizon device - Money, K. E
Peripheral Vision Horizon Device (PVHD) theory states that the likelihood of pilot disorientation in flight is reduced by providing an artificial horizon that provides orientation information to peripheral vision. In considering the validity of the theory, three areas are explored: the use of an artificial horizon device over some other flight instrument; the use of peripheral vision over foveal vision; and the evidence that peripheral vision is well suited to the processing of orientation infor...

[texts]Chemical nonequilibrium effects on the inviscid flow in the windward plane of symmetry of two simplified shuttle configurations - Lordi, J. A.
A theoretical study was made to delineate the effects of thermochemical nonequilibrium in the inviscid flow field of a representative space shuttle orbiter configuration. The study was based on experimental pressure data which was used as an input to a stream tube computer program. The pressure data from two configurations are tabulated. Calculations were restricted to the windward plane of symmetry and the calculations covered an altitude range from 200,000 to 250,000 feet at velocities of 16,0...

[texts]Keeping a Spacecraft on the Sun-Earth Line - Roithmayr, Carlos M.
Measurements of Earth's atmosphere as it occults sunlight can be obtained advantageously from a spacecraft placed in the proximity of the Sun-Earth Lagrange point L2. Maintaining the condition of continuous solar occultation by all parts of the atmospheric disk requires that the displacement of the spacecraft perpendicular to the Sun-Earth line remains less than 200 km. However, the gravitational force exerted by the Earth's moon must be negated by propulsion in order to meet this rather tight c...

[texts]The effect of system nonlinearities on system noise statistics - Robinson, L. H., Jr
The effects are studied of nonlinearities in a baseline communications system on the system noise amplitude statistics. So that a meaningful identification of system nonlinearities can be made, the baseline system is assumed to transmit a single biphase-modulated signal through a relay satellite to the receiving equipment. The significant nonlinearities thus identified include square-law or product devices (e.g., in the carrier reference recovery loops in the receivers), bandpass limiters, and t...

Little is known, however, about the frequency and location of these fires, and the area burned each year...
